pH-Responsive Copolymer Assemblies for Controlled Release of Doxorubicin

Gillies, Elizabeth R., Fréchet, Jean M. J.·2005·Bioconjugate Chemistry

Abstract

pH-Responsive drug carriers have the potential to provide selective drug release at therapeutic targets including tumors and in acidic intracellular vesicles such as endosomes and lysosomes. We have developed a new approach to the design of acid-sensitive micelles by incorporating hydrophobic acetal groups on the core block of a micelle-forming block copolymer. Hydrolysis of the acetals at mildly acidic pH is designed to reveal polar groups on the core-forming block, thus changing its solubility and disrupting the micelle, triggering drug release. The anticancer drug doxorubicin (DOX) was encapsulated in these pH-sensitive micelles, and the acetal hydrolysis rates and DOX release rates were determined in the pH range of 4.0 to 7.4 and were compared to those of control systems. The micelle disruption was investigated by dynamic light scattering. The in vitro toxicities of the empty and DOX-loaded micelles were determined, and the intracellular fate of the encapsulated DOX was compared to free DOX using fluorescence confocal microscopy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
